6.The fundamental difference between electromagnetic waves and other types of waves is that electromagnetic waves

move more slowly than all other types of waves. are invisible regardless of wavelength. do not experience constructive or destructive interference. transfer energy without transferring mass. all have the same wavelength.

7.Another word for constructive interference is

amplitude. destructive. reinforcement. Doppler effect. acceleration.

8.The scattering of light waves from the surface of an object is called what?

reflection scattering refraction absorption

9.What happens when two waves from different sources come together at a single point? (Points : 1)
